Spiders can be beneficial to your home.
They are predator animals that feed primarily on insects. There are
certain spiders that can be dangerous, however. These are poisonous
spiders. Luckily, in the United States, there are very few types of
poisonous spiders which live in the country.
Most experts believe that the Brown
Recluse is the most dangerous American spider. Part of this is
because the Brown Recluse is so tiny and unassuming. Unlike larger
spiders, Brown Recluses can be hard to spot. They also prefer dark
corners and cracks, which can make it easier to accidentally happen
They range between 1/4th and
3/4ths of an inch in length. They have long legs for their
size, and they are solid brown in color. Brown Recluses can be found
from California to Georgia, but they are primarily found in the
Southern states and the Lower Midwest. Their defining characteristics
are that they have a violin-shape on their back, and that they have
six eyes instead of eight.
Brown Recluse bites lead directly to
tissue destruction and necrosis will eventually set in. The venom of
these spiders can lead to death in many cases. Luckily, Brown
Recluses are not aggressive, and will only strike when cornered or
This is probably the most famous spider
in the United States. Unlike Brown Recluses, Black Widows are
incredibly easy to spot, because of the identifying hourglass shape
on their backs. Adult Black Widows are almost always the same size,
around half an inch in length. Black Widows can be found all over
Black Widows seek out areas of
cluttered, undisturbed peace, whether they be indoors or outdoors.
They like garages, sheds, stumps, stones, and wood piles, and build
nests close to the ground with a mixture of webbing and various forms
of matter they accumulate.
Black Widow poison is incredibly
dangerous, and strikes the nervous system directly, causing
hypertension, vomiting, headache, and abdominal pain. Luckily, there
is highly effective anti-venom for the Black Widow Spider bites that
vastly reduces the risk to life and limb.
Their bodies are around half an inch
long, but with their legs, they can be as long as two inches. They
are light brown with dark brown abdomens, and they can also be
identified by their mouths, attached to two mouth structures that
look a lot like boxing gloves.
Hobo Spiders are not nearly as
dangerous as Black Widows and Brown Recluses, but they can still
cause major health issues. These spiders live exclusively on the
ground, and build their webs at ground level as well. They can be
found both inside and outside.
Hobo Spider Bites cause headaches which
can last anywhere from two to seven days, and can cause fatigue and
weakness, as well vision and memory problems.
Yellow Sac Spiders
These spiders are venomous, but not
very dangerous. You don't want to get bitten by one, but you won't
suffer too badly if you do. Their bites generally cause skin
irritation, and can lead to water retention and temporary arrhythmia.
These spiders are primarily nocturnal,
and are considered to be the most common source of annoying bites in
America. Yellow Sac Spiders wander around at night, and generally
bite because they crawl on sleeping humans and feel threatened by
body movement. They are naturally yellowish-white in color, but their
color changes according to their most recent meal. The area covering
their fangs is usually black.
